foveiform at apex; elytra nearly a third longer than wide, wider 

 posteriorly as usual, twice as wide as the prothorax; striae fine, 

 distinctly impressed except apically, the seventh extremely fine and 

 unimpressed or obsolete as in the two preceding, the intervals 

 moderately convex, flatter toward apex. Length 4.3-5.8 mm.; 

 width 1.75-2.6 mm. Wisconsin, Indiana, Mississippi and Louisiana.

4 — Head with fine but deep sparse punctures. Body very small in size, 

 shining, piceous, the head black; prothorax with pale side margins; 

 elytra each with an irregular discal pale spot, somewhat oblique 

 and before the middle, the tips pale, more broadly so internally; 

 under surface and legs pale, the head dark; head four-fifths as wide 

 as the prothorax, with rather large and prominent eyes, the tempora 

 moderately converging; antennae fuscous, clearer basally, half as 

 long as the body; prothorax three-fifths wider than long, widest 

 before the middle, with very moderately rounded and widely reflexed 

 sides, briefly and feebly sinuate at the distinct hind angles; rugu- 

 losity fine, sparse and inconspicuous; median line distinct but not 

 attaining the apex; elytra one-half longer than wide, two-thirds 

 wider than the prothorax, parallel, rounding at the sides apically; 

 striae relatively rather coarse, irregularly subpunctate, the intervals 

 feebly convex, perfectly flat apically, where the striae become very 



fine. Length 3.0 mm.; width 1.5 mm. Virginia lobulata Lee. 



Head not at all punctured, smooth, sometimes slightly rugulose later-

5 — Head small, elongate, about two-thirds as wide as the prothorax.. .6 



Head larger, not elongate and with more prominent eyes 7 



6 — Body not stout, moderately convex, shining, black, the prothorax 

 more piceous, with the broadly reflexed margins pale; elytra each 

 with a discal pale spot before the middle, never attaining the sides 

 or base, and a smaller rounded pale spot near apex and adjoining 

 the first stria; under surface and legs pale, the prosternum and 

 abdomen piceous; head nearly smooth throughout, the eyes only 

 moderately prominent, the anterior superciliary puncture notably 

 large; antennae slender, rather more than half as long as the body, 

 fuscous, the first three joints paler; prothorax two-thirds wider 

 than long, widest before the middle, the sides moderately arcuate, 

 straight basally, the angles minutely and bluntly subprominent; 

 surface nearly smooth, the rugulae fine, sparse and faint; median 

 line fine, impressed, not extending anteriorly beyond the angle of 

 the fine and feeble transverse impression; elytra fully a third 

 longer than wide, gradually inflated posteriorly, barely twice as 

 wide as the prothorax; striae coarsely impressed, uneven or feebly 

 punctate; intervals moderately convex. Length 4.0-5.0 mm.; 

 width 1.7-2.0 mm. Rhode Island to Indiana. Abundant. [L. 



frigida Chd.] ornata Say 



Body broader than in ornata and with much more developed pale elytral 

 maculae, shining; head black, the prothorax pale flavo-testaceous, 

 with a median piceous cloud, the elytra black, each with a very
